Title: Method for operating a generator, and circuit for carrying out the method
Inventor: BARTSCH KNUT
IPC: H02K3/28
Filed: 1997-07-04
Abstract: The invention relates to a circuit for operating a generator having a plurality of generator coils in which a voltage is induced. At low rotational speeds and/or low voltage output, at least two of the generator coils are connected in series, and at higher rotational speeds and/or at a higher voltage output of the individual generator coils, the latter are connected in parallel, with the result that the generator voltage of the generator is reduced.      As a result of this, the total voltage of the generator is kept in a predetermined range in a simple manner, without complicated voltage regulators being necessary for this purpose. In addition, high output voltages which enable operation of electrical devices, in particular fuel injection devices, are obtained at low rotational speeds.

Title: Modular, high-voltage, three phase recloser assembly
Inventor: MATHER BRIAN D
IPC: H01H33/666
Filed: 1999-05-19
Abstract: In accordance with the present invention, a recloser assembly including three modular recloser units operating under the control of a controller. The recloser units are interchangeable and are suitable for use in a three phase power distribution system where three phase tripping is desired or each recloser unit may be operated independently as in a single phase power distribution system. For use in a three phase system, a gang rod mechanically couples pivoting actuation levers extending from a solenoid switching assembly of each of the recloser units. The gang rod insures that all three switching assemblies open and close in unison, thus, each power is transmitted by all three recloser units or power is not transmitted by any of the three recloser units. For single phase power distribution operation, the gang rod is removed and the recloser units operate independently. Each recloser unit includes a cube shaped base, a tapered cylindrical support affixed to an upper surface of the base. The support includes a first opening to receive a ceramic insulator supporting a switch terminal and a second threaded opening to receive a bushing and polymer insulator supporting a line terminal. Each recloser unit utilizes a vacuum interrupter switch or terminal contact assembly to contain electrical arcing and maximize terminal contact life. The interior region defined by each support is filled with an environmentally friendly, nonvolatile insulation material. An interior region of each base houses a solenoid switch assembly and a pressure equalization assembly.
